Fire barrel type gas burner

Abstract

Aiming to solve the problems that a hearth of gas-fired heat power equipment is not uniformly heated, the local heating surface of the hearth is overheated and subjected to burning loss, and the like, the invention provides a fire barrel type gas burner, which can be structurally divided into two parts, including an air intake and distribution device at the front part and a tubular combustion chamber at the rear part, wherein the air intake and distribution device at the front part includes a center combustion air passage, an annular fuel gas passage and an injection air passage which are coaxial and arranged sequentially from inside to outside; and the tubular combustion chamber at the rear part is a steel barrel provided with an opened tail part on the whole. The fire barrel type gas burner has the advantages that the center combustion air introduced in a forced manner improves the ability of the gas-fired equipment in jetting the outside air, and the overall excess air factor of the gas-fired equipment can be controlled through adjusting the combustion air introduced from the center in a forced manner; and the shape of the gas flame can be effectively controlled through the length and the pipe diameter of the tubular combustion chamber, so that the tubular combustion chamber is reasonably matched with the hearth space, and the problems that the hearth is not uniformly heated, the local part of the hearth is overheated and subjected to burning loss and the like are solved.

Description

technical field [0001] The invention relates to a gas burner. Background technique [0002] Due to the needs of practical engineering applications, in the design of many gas thermal equipment, the furnace is designed as a long space with a relatively large length and diameter. In the application process of this type of gas thermal equipment, a large number of problems such as uneven heating of the furnace and overheating and burning of the local heating surface of the furnace have occurred. The reason for the above-mentioned problems is mainly because the existing gas burners used in conjunction with gas thermal equipment have poor ability to organize long flames. Concentrated heat release in the local space in the furnace, which in turn leads to problems such as uneven heating of the furnace and overheating and burning of the local heating surface of the furnace. Contents of the invention [0003] The invention can successfully organize a long flame with a relatively la...
